One year ago — on Aug. 5, 2015 — an EPA crew at the Gold King Mine in southwest Colorado accidentally unleashed 3 million gallons of orange water filled with mercury and arsenic.

The toxic spill flowed into the Animas River, eventually running into New Mexico's San Juan River and into Lake Powell. So far, disaster response and water quality monitoring have cost the EPA about $29 million — and the problem isn't over yet.

Mesa Verde National Park in southwest Colorado is known for its iconic cliff dwellings, but archaeological artifacts left by the Ancestral Pueblo are all over. Rocky remnants of homes and farming sites are scattered throughout the dense pinyon juniper forest.

The rates will go up despite the fact that visitation at parks is up, which means bigger crowds, congested traffic and busier visitor centers. But more people aren't translating into a big boost for park budgets. For example, visitation at Rocky Mountain National Park in Colorado is up 20 percent so far this year and Yosemite, Yellowstone and Zion are also seeing double-digit increases. The parks are also seeing the strain. About 100 parks are planning an entrance fee hike.

It's a refrain many in the state have grown to loathe this summer — heard outside their favorite grocery store or shopping mall as signature gatherers race toward an Aug. 4 deadline to put four energy-related measures on the November ballot.

With two of those measures backed by environmentalists, and the other two by industry-supported groups, all of the energy talk is leading to confusion among potential voters.

The indoor shooting range at Archery in the Wild in northern Colorado used to be dominated by camouflage and hunters. But on this Saturday morning, the archery range is dotted with ponytails and 7-year-old girls like Y'Jazzmin Christopher.

The popularity of The Hunger Games series is fueling an interest in the sport of archery, particularly among girls. Some sporting equipment outfitters say they've seen a big boost in bow and arrow sales since the film series began in 2012.

The heavy floodwaters in Colorado this month caused more than 37,000 gallons of oil to spill into or near rivers, and the state's oil and gas industry is rushing to fix equipment damaged during the storm. It comes at a time when there's growing public concern about the environmental effects of hydraulic fracturing in the state.
